Confusion Matrix for Classification on the Training-Testing Set

n=44 Predicted Stage C Predicted Stage D
Actual Stage C 30 (TP) 3 (FN) 33
Actual Stage D 4 (FP) 7 (TN) 11
34 10

TP = True Positive, FN = False Negative, FP = False Positive, TN= True Negative

Accuracy = 0.84, Sensitivity = 0.91, Specificity = 0.64, Positive predictive value = 0.88 and Negative predictive value = 0.7
